MEANS FOR HUMIDIFYING ARTIFICIALLY HEATED AIR.

Application filed March 23, 1914.

To rzL Z whomit may concern Be it known that I, ADDISON A. Cannwnnn, a citizen of the United States, and a resident of Rye, county of Westchester, and State of .Tew York, have invented certain new and useful Improvements in Means for liumidit'ying Artificially-Hented Air, of which the following is a specification.

My improvements relate to humidifying appliances and are designed primarily to adapt, to steam or hot water radiators, my system of compensating for lack of moisture in artificially heated air by utilizing the heating means to supply, in whole or in part. the deficiency otherwise created thereby. as in my concurrent applications No. silt-HM. filed Feb. illth, 191 and No. 523.036, filed hlar. 16th, 1914-.

To this end the present invention consists more particularly in the specific construction and arrangement of parts described and claimed herein.

lluids issuing therefrom and exposed to the atmosphere and to the heat from the radiator and so formed as to offer substantially no resistance to the fluids issuing from said conduit.

In the accompanying drawings, Figure 1, represents an end view of the top portion of a hot water radiator provided with means for utilizing hot water from the radiator for the purpose of humidifying the air heated by said radiator: Fig. 2, is a top view of the parts shown in Fig. 1; Fig. 3, a side elevation thereof: Figs. 4. 5. and. (i. are views like unto the first three figures. showing the application of my humidit'ying means to a steam radiator: Fig. 7, is a top view of the fluid vent or escape valve which is interposed in the conduit between the radiator and the evaporator; l ig. S, is a central longitudinal s'ectiona'l ,elevation of the same; Fig.9. is a sectional ele 'ation of the reservoir for volatiles, and the evaporator, the latter broken away in part. Fig. 10, is a sectional detail of a modification of the evaporator.

The main object of the invention is the utilization of the heating'fiuid as a humiditying agent to render the air heated by the radiator less deleterious to health and comfork-to counteract in oot the evil elleets of overheating and dryness produced In the surrounding air by direct convection and Specification of Letters Patent.

radiation from the surface of the radiator.

And for this purpose the usual air ventssymbolical representation of the upper part of an end loop R, of a hot water radiator, the usual top or high tap 7 provided for the usual air vent, is used as a means of attachment for my valve casing V, whereas in the succeeding three figures R, represents the end member of a steam radiator, and in like manner the usual-low tap 9*, provided for the customary airvent, is utilized to make connection with the valve casing V. By preference a screw needle valve a, is mounted in the casing V, controlling the availabl arf the vent duct r, as shown in Fig. o, )Ufh any form of valve may be substitute. t so desired. The outer end of the valve stem may be flattened or angir lar in cross section to afford means for engagement with a wrench or turning implement, or an index pointer p, attached to the valve stem may be utilized as a handle,-a concentric index 2', on the casing V, being provided for use in conjunction with the pointer ,1), to assist in setting and regulating the How.

Interposed between the connection with the radiator loop R, or R, I prefer to use a filter chamber F, containing a filtering medium 7", adapted to eliminate from the out-flow from the radiator any sedimentary or foreign matter that may be carried over by the fluid pressure, so that only pure water or moist vapor escapes through the vent r, to the absorbent evaporative medium m. This filter is preferably placed between the radiator-and the vent u. as shown in the drawings, particularly Fig. 8, in which the casing for the filter is attached directlYto the 'alve casing V, the filtering material being held in place between arched foraminous partitions f, F.

The absorbent evaporativc medium m, may obviously be arranged and supported in various ways without departing from the spirit and intent of my invention in this respect, provided it isarranged in juxtaposition to the radiator so that the heat emanating therefrom will insure the vaporize tion of the moisture absorbed by the mater al m. An effective arrangement is to no sition absorbent evaporative material. m, longitudinally {as related to the length of the Whole radiator) Within the central paces 7*", between the vertical members of he loops, as indicated in the drawings, this rrangement afiording a maximum or" heat evaporative purposes While isolating and protecting the evaporative device. The latter may consist simply of a conduit pipe 0, communicating with the vent port o, in the valve casing V, the other end of said conduit 0, being connected with. a ioraminous tube or cylinder t, (Fig. 9) preferably of non-corrosive material, in which the absorbent evaporative medium m, is positioned; or any other equivalent means of supporting said absorbent evaporative medium and presenting within the heating are oi the radiator (thev nearer the latter better Without actual. contact therewith) may be substituted; as may also other means of moistening' the evaporative medium m, ith moisture obtained from the radiator elf, the utilization of the heating fluid ror this purpose being the essential feature in this respect. In the modification shown in 10, the evaporative medium m, consists ofa cloth or textile fabric hung over conduit 0, which is perforated to allow moisture to drip into said pendent operative medium.

Since the heating fluid, Whether hot aer i r steam, is apt to contain elements that when liberated therein, 1 connect the conduit with a reservoir a, for volatile material he emanations from which pas sthrough due a, into conduit 0, as illustrated .rticularly in Fig. 9. lhus the fluid the absorbent evaporative medium P may be impregnated automatically with deodorant, disinfectant, erfumery or medicement as he found most expedizupart a disagreeable odor to the atmosphere was cut, and this method of surcharging the humidified air will be found most efiicacious in the treatment of disease? unsanitary conditions, or unpleasant olfactory environment, &c.

All this is accr i hed Without interfering With. the use or my device as an ordinary air vent for the radiator; and the device, in Wholeor in part, is adapted for permanent incorporation With a radiator as fitted for the market, or as an attachment to radiators already installed. and in use.

What I claim as my invention and desire to secure by Letters Patent is,

1. A. humidi' ying attachment for radiators, comprising a casing with means for attachment to the air vent of a radiator, a pipe leading from said casing, an absorb cut medium supported by said pipe and arranged to he moistened. by the fluids issuing therefrom and exposed to the atmosphere and to the heat from the radiator and so formed as to Oder substantially no resistance to the fluids issuing from said pipe.
